Definitions

  • This invention relates to a device for adjusting the flex, particularly in rear-entry ski boots.
  • ski boots have long been equipped with devices allowing the amount of flex thereof to be adjusted, that is, for adjusting the bias action applied by the cuff in skiing practice.
  • Various types of devices are currently in use, for flex adjustment, which generally comprise a settable elastic means connected between the shell and cuff of the boot to enable the user to vary the elastic bias as desired.
  • This type of a device is not, however, applicable on rear-entry ski boots, wherein the rear cuff must be left free to pivot out such that the boot can be worn, since such devices would hamper the user during the boot putting on operation.
  • the task of this invention is to provide a device for adjusting the flex of a ski boot, which is specially conceived for use with rear-entry ski boots, wherein the device itself would not hamper the user in putting on the ski boots, and which is so set up as to require no special or complex handling to put the boots on.
  • Another object of the invention is to provide a device which, owing to its constructional features, can be fully reliable and safe to use.
  • a device for adjusting the flex particularly in rear-entry ski boots, characterized in that it comprises, within a receiving seat defined in the rear cuff of a ski boot, settable elastic means connected to an engagement element protruding out of said receiving seat, said engagement element being adapted to engage, with said rear cuff in the closed position, with a retaining element provided rearwardly on the shell of said ski boot.
  • FIG. 1 shows schematically the device of this invention as applied on a rear-entry ski boot
  • FIG. 2 is a longitudinal section view of the device of this invention, with the cuff in its closed position;
  • FIG. 3 is a sectional view of the device with the cuff in its open position
  • FIG. 4 shows schematically a front view of the device.
  • this device for adjusting the flex particularly in rear-entry ski boots, comprises a shape seat 1 which is defined close to the bottom end of the rear cuff 2.
  • settable elastic means which, in this instance, include a link 3 of substantially U-like shape and having its arms 3a accommodated within the seat 1, and the arm interconnecting portion thereof, 3b, located externally of the seat and protruding below the bottom end of the cuff 2.
  • cylindrical coil springs 4 which act, with their bottom ends, on the base of the seat 1, and precisely on a metal reinforcement 5 attached to the seat itself, whilst with their top ends, the coil springs 4 act on a setting plate 6, which has at its center a threaded seat 7 wherein a threaded shank 8 of an adjusting pin 9, protruding up from the seat 1 and having at a middle portion thereof a flange formation 10 adapted to abut against an abutment plate 11 which is located below bolts 12 mounted on the free ends of the arms 3a, can be engaged rotatably.
  • a peculiar feature of the invention is that the arm interconnecting portion 3b forms an engagement element adapted to engage with a retaining element 20 provided rigid with the rear portion of the shell 21.
  • the retaining element 20 has a downwardly open hooked configuration, whereby it allows the interconnecting portion 3b to disengage automatically as the rear cuff is pivoted rearwards to open the boot, and to automatically engage the portion 3b as the cuff is moved into its closed position.
  • the device is provided with an unobstructed area 30, shown in dash lines in FIG. 4, in the seat 1, which is effective to allow the retaining element 20 freely through the device as the cuff is pivoted.
  • the retaining element When the boot is to be put on, by pivoting the rear cuff out, the retaining element is caused to disengage from the interconnecting portion 3b, thus allowing the boot to be opened, with the added advantage that the device, being carried on the cuff itself, will in no way interfere.
  • the retaining element 20 is practically caused to slip onto the interconnecting portion 3b, thus re-establishing the connected condition and allowing in consequence the cuff to be swung with respect to the shell by merely overcoming the bias force of the elastic means.
  • the invention achieves its objects, and in particular that the device construction is simple, while it interferes in no way with the unimpeded rearward pivoting of the rear cuff to put the ski boot on.
  • the materials used if compatible with the specific application contemplated, as well as the dimensions and contingent shapes, may be any suitable ones meeting individual requirements.
